Just had a house built and the builder installed a Honeywell HE365 who house humidifier. I originally planned to upgrade to a Truesteam humidifer, but I now know the cutout for the HE365 is large on the ductwork and the Truesteam is just a small hole. Meaning I either have to patch the old hole or determine if a new thermostat I want can control the humidifier? Not sure how I could patch a 12"x9" hole in the ductwork? Buy extra metal, cut oversized, screw it in and aluminum tape around the edges? Or can I somehow get a new Honeywell Prestige thermostat control the humidifier? Or b/c this model humidifier is basically a dumb powered model will it not work with a separate thermostat?
